Scapping is fishing for soft shell crabs with a simple long pole net.

Sistering is reinforcing a weak part by attaching a stronger one
alongside. On a boat its sometimes used to describe a new frame placed
alongside a cracked frame.

1 pt. See Joe's post. :-)

Actually "scabbing" is sometimes used for scapping, so my answer holds.

However, since you mention scabs with sistering, I'm guessing you mean the
little sister plates you might use to form a "t" or to join timbers. You
see them on house trusses. On a boat they might be used to join a two
part frame.

So how many points do you lose for getting the term wrong?


I was thinking of when you join two pieces of wood on the same plane...
flush, not a T.

So, I'll take -0.5 points from myself, and remove your 1pt. :-)

I was talking about flush joints, where the scabs are small sisters on
the sides of the joints. The "T" that I mention has the timbers all
on the same plane, with through bolts through scabs to hold it
together. I mentioned this because its where I first learned of
scabbing, when building roof trusses. Nowadays, with metal truss
plates, I think scab usually refer to repairs.

'sistering', going below with two sisters at the same
time.

Do they have to be sisters?


For me, yes. You prefer brothers?

Ok. I'll give you back 0.5 points.... just because I'm a nice guy. :-)

I prefer two hot looking women, but she-who-must-be-obeyed wouldn't go for

Neither term is really specific to boats. Scapping is the use of a long handled
net for crabbing, and sistering is construction reinforcement where you attach
an additional timber to an existing one to add strength.

Correct, I sistered my ceiling joists in order to create a room in my
attic and by the act of "sistering" they could bear the live loads as
floor joists.

Wrong

For example (as Jeff said) a frame in a wooden boat can be sistered
but the new frame isn't attached to the old one.

Yep.

If it was spars, you'd call it a fish

Or somebody who crosses a picket line for work.

From Hammerzone.com but many other references

What Is Joist "Sistering"?

Sistering a joist simply means attaching more material to the side of
the joist. This can mean a new joist of the same size and length is
screwed or nailed firmly to the old joist, or it can be a smaller
structural member. Sistering could also involve sandwiching the old
joist with new material on both sides. Typically this involves framing
lumber, but it could involve engineered lumber, structural steel or
formed steel joists that are made of heavy gauge sheet metal.

That may be true of joists but not boat frames.

BTW to call somebody a "house carpenter" is is considered an insult
among boatbuilders.

Sistering is a very inefficient way to increase the strength of a member.
Doubling the member's thickness only doubles it strength. Increasing it's
width (or height) increases the strength as the cube of the dimension.
{Deflection ~ Young's modulus x moment of inertia}.
